I was thinking more a way of getting the memory usage using run.d (the 
app I'm using for benchmarking, it's in the repository if you're 
interested). It's rather difficult to get the memory usage in run.d so I 
can put it straight into the stats page if it's being got from within 
benchmark, and doing this would probably affect the benchmark some 
amount which I would ideally like to avoid.
